Title: Mast tilting speed control device for industrial vehicle
Inventor: GOTO TETSUYA
IPC: B66F9/22
Filed: 1999-08-23
Abstract: PROBLEM TO BE SOLVED: To simply control a mast to have an optimum tilting speed in consideration of a load and a lifting level. SOLUTION: A hydraulic pump for supplying hydraulic fluid to a tilting cylinder 2 for tilting a mast 1 is driven by a cargo handling motor (electric motor) 17 and the tilting speed of the mast 1 is determined by the rotating speed of the cargo handling motor 17. A lifting level sensor 5 detects whether the lifting level of a fork 4 is low or high. A ROM 52 previously stores a map diagram (map data) showing torque-rotating speed property for each of low and high lifting levels. When a tilting level 6 is operated and either of a detection switch 9 or 10 is turned on, a CPU 51 selects the map diagram corresponding to the lifting level detected by the lifting level sensor 5 and outputs a command signal corresponding to the map diagram to a cargo handling motor driving circuit 57.  The cargo handling motor 17 is controlled to obtain the torque-rotating speed property determined by the lifting level. The cargo handling motor 17 is controlled in the lower rotating speed for the heavier loading weight (load).

IPC: H03H17/02
Filed: 1988-09-22
Abstract: PURPOSE: To apply this device even to the number of channels which is not equal to the power of 2 by not operating the designing specification of a demultiplexer to the next higher power 2.Lo of 2, and operating the no load operation of 2Lo -L' channels at that time.

Moreover, an input side frequency multiple signal is real for the first stage, and a sampling rate at the input side of the first stage is reduced to 1/2. That is, the total number of channels to be demultiplexed(multiply separated) is increased from power L0 =2i of 2 to L' (here, L0 < L'<210 , and an input frequency fsi =410 .B is maintained). Thus, this device can be applied even to the channels in a number which is not equal to the power of 2.

Title: Sea water flow passage facility
Inventor: UMENO YUKIKO
IPC: E02B3/00
Filed: 1991-09-18
Abstract: PURPOSE:To prevent deterioration of heat exchangeability by changing over the flow direction of sea water properly in a sea water flow passage excluding a strainer, thereby eliminating clogged portions in the sea water flow passage and preventing production of deposits. CONSTITUTION:Sea water 4 is flowed into a heat exchanger 1 through a strainer 5, a strainer outlet pipeline 11a, a strainer outlet changeover valve 12a, and a heat exchanger pipeline 6a. Heat removal is performed therein by heat exchange in between a cooled member 3. Then, the water is discharged into the sea through a heat exchanger inlet pipeline 6b, a water discharge changeover valve 13b, a water discharge pipeline 8b, a water discharge pit 7b. When the strainer outlet changeover valves 12a, 12b and the water discharge changeover valves 13a, 13b are alternately changed over every specified time, the flow direction of the sea water is changed, so that clogged portions in the respective passage are changed. Deposits once deposited is thus removed by the sea water whose flow direction has changed and flowed into the sea.

Title: Occupant detection system
Inventor: JINNO KAZUNORI
IPC: B60R21/01
Filed: 1997-09-03
Abstract: PROBLEM TO BE SOLVED: To easily detect whether an occupant is seated on a seat or not by detecting an electric current flowing in a transmission signal system by an electric current detection circuit. SOLUTION: A weak electric field is produced in accordance with high frequency low voltage supplied to an antenna electrode 5 from an oscillating circuit 21 in a periphery of the antenna electrode 5, and an electric current flowing in accordance with this weak electric field differs in accordance with an object existing on a seat 1B. Additionally, a phase difference between a transmission signal from the oscillating circuit 21 and an output signal to the antenna electrode 5 on the side of the oscillating circuit 21 and the side of the antenna electrode 5 of an electric current detection circuit 25 also differs in accordance with the object existing on the seat 1B. Especially, in the case when the object is a human, it has a phase difference of a level in a degree free to recognize in comparison with other objects.  Consequently, it is possible to highly precisely detect whether an occupant is seated on the seat 1B or not easily as well as to judge it with a signal data in connection with a detected electric current by detecting the phase differences by a phase difference detection circuit 29.
